What are blocks in a transposition cipher?
[The blocks are the units you break the letters into in order to encrypt it.
So if the text had sixty letters, you might break it into 4 blocks of fifteen letters each, then encrypt each block separately:
THEBL
OCKSA
RETHE
UNITS
YOUBR
EAKTH
ELETT
ERSIN
TOINO
RDERT
OENCR
YPTIT
